The change reportedly won't take place until 2020, though.

The annual Detroit motor show – or North American International Auto Show, as it's known officially – could move from its traditional January start date, according to reports from local media.

Detroit News reports the Detroit Dealers Association wants to move the event, which has been shrinking in the shadow of the Consumer Electronics Show (CES) in Las Vegas, to later in the year, likely in July or October.

The change reportedly won't take place until 2020, at which point the Cobo Centre in downtown Detroit will have the facilities to host a massive in/outdoors festival, more in keeping with the likes of Goodwood. Don't expect a hillclimb, mind you.

A proper announcement is scheduled for July 24, but the Detroit News reports a 25-second teaser video depicting a 'festival' style event has been put together.

Along with the date change, the Dealer Association is talking about a change of name to highlight the fact the show is in Detroit.

The change is likely driven by a global move away from traditional motor shows. BMW and Mercedes-Benz are already skipping the next Detroit motor show, while this year's Paris show is likely to be missing a number of crucial big brands.

Manufacturers are looking instead to tailored events, launching their big models on their own schedule, with events designed to highlight their strengths – rather than generic press conferences, timed to make the Detroit Dealer Association happy.
